Nonmetals are usually poor conductors of heat. They are found on the left side of the Periodic Table and the middle. Also all the lanthinide series are metals, as well as the artificial radioactive ones past uranium.

∙ 14y agoIn general, whole molecules are poor conductors while ionic solutions are (comparatively) good ones. Pure water has a very small ionic content (its molecular bonds are primarily covalent) so it conducts electricity, but poorly.
Addition of a substance whose molecules are ionicly bonded (if it is water soluble) will increase the ionic content, and therefore the conductivity. These include many salts (including table salt) and most acids and bases. But you want to know what solutes don't increase conductivity.
Molecules that are primarily covalently bonded generally don't break apart into ions when dissolved. Covelent molecules are usually organic chemicals, and a great many of those are not soluble in water. But some are. They include (here's the answer you were actually looking for):- Alcohols (ethyl, methyl, isopropyl, and others);
- Sugars (sucrose, glucose, fructose, etc.);
- Some common solvents, such as acetone;
- And many more.

What is the type of mixture whose components are even distributed throughout?
A homogeneous mixture.
A mixture whose parts are the same throughout?
Solution is the correctanswer according to my science book!!!
Is chalk a mixture or a solution?
Chalk is Calcium Carbonate, aka CaCO3, so it's only one substance.
What is the difference between electrolytes and nonelectrolytes?
electrolytes react with water to form ions in solution, and nonelectrolytes have molecules.Electrolytes are ionic compounds and some covalent compounds like strong acids. Non electrolytes do not ionize in water. Only covalent compounds like CH4 and C6H6 can be nonelectrolytes-----------------------------------------------------------------------------------------------♥Compounds whose solutions in water or whose molten states are capable of conducting electricity are called electrolytes. They are either acids, bases, or salts. Solutions of these compounds contain ions. Electrolytes which in solution are completely or almost completely in the form of ions are called strong electrolytes. They are very good conductors. Those whose solutions contain mostly covalent molecules are poor conductors of electricity and are called weak electrolytes. Non electrolytes are compounds whose solutions DO NOT conduct electricity. ^^;
What does semiconducter mean?
A semiconductor is a type of conductor whose conductibility is between a conductor and an insulator. They are typically used as parts of items like electrical circuits.
Which is a molecular substance whose water solution conducts electricity?
This is an ionic compound dissociated in water.
A solution whose solute cocentration of a substance is the throughout a space?
solute
Is a brass paper fastener a conducor?
Yes, because it is metal it is. :)
A water solution whose pH is 10?
Is always basic.
Gas whose aqueous solution is basic?
Ammonia gas when dissolved in water produce Ammonium hydroxide so its solution is basic.
What kind of compound whose water solution conduct electricity?
Ionic or electrovelent or polar compounds
Is pure substance uniform composition?
a pure substance. either a compound or an element. Also, a solution, which is a homogeneous mixture, not a pure substance.
What does it mean for a substance to be semiconductor?
A substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities. :) Hope that helped;)
What is a substance whose meniscus would curve downward?
Mercury's meniscus curves down. Water's meniscus curves up.
A Cell is placed in a salt solution whose concentration is greater than cell?
When a cell is placed in salt water it will shrink, but will swell in carbonated water. m.c
Is a carbonated soft drink a solution mixture or compound?
A soft drink is definitely a compound. You see, mixtures can be easily taken apart. A salad is an example of a mixture. A compound is a substance whose smallest unit is made up of atoms of more than one element bonded together. This just means that compounds cannot be separated easily. A soft drink, air, and carbon dioxide are some examples. A solution is sort of like a compound, except that a solution is a substance mixed into another. Some examples are table salt water- when you mix table salt into water- and powder lemonade when you mix it in water. In all solutions there is a level of solute. If you exceed this level, the solution will not mix all the way and you will be left with a substance you can see because it has overpowered the other.
What do you use universal indicator solution for?
It is a chemical solution used for knowing the pH of a substance. Eg. You mix a drop of Universal indicator solution with approx 5 mL of the substance whose pH you want to know.You can compare the color with a standard pH chart and know the pH.
